`IMPROVMENT lN ROLLED BARS FOR PLOW-BEAM B-LANKS.

The Schedule referred to in these Letters Patent and making part of the same.

To all 'whom fit may concern: z

Be it known that we, GEORGE WrJorn and WIL- LIAM BUNTOX, both of `Pittsburg, inthe county oiAllcgheny and State'of Pennsylvania, have invented a new and nseful'artiele of manufacture, riz., Blanks for Plow-eauisg and wc do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing and to the let-ters of. reference marked thereon.

'lhc nature of our invention consists in a new article of manufacture, riz: A bar of iron or steel rolled into the form hereinafter describethforthc purpose of forming a. continuous series of blanks for plow-beams.

To enable others skilled in the art to inakcand use our new articleef manufacture, we will proceed to describe more fully its construction. t

In the accompanying drawing- Figure l is a side view of a bar of iron rolled into a' series of blanks for plow-beams.

Figure 2 is a top view of the salue.

Figure is a transverse section of the bar of iron at line y'offigl.

Figure- 4 is-a transverse section of the bar of iron at B represents that portionot" the beam which is forward of the standard.

To make our new article of manufacture, we take a. bar of iron which iu thickness and width is equal to the thickness and width of the widest portion of the plowbeam, which is indicated in t-he drawing at the liuc y of tie. 1.

oBein g properly heated, we pass it ou its edge through suitably-constructed rolls, which will draw the bar out into the form represented iu fig. l. \Ve then pass it through a plain pair of rolls, which will work in the fash or in, and. uish it ready forV use. The blanks-are separated bycutting the bar through at lines y and y". l

The construction of the rolls for rolling our new article 0f manufacture, wev leave to the skilful roll-turner,

andthe manner ot' using the rolls to the skilful roller.

lhe advantage of constructing blanks for plowbeauls in the manner hereinbeforc described, consists in the saving of labor of forging aud shearing and making thein of a uniform size and superior finish with increased strength of structure, which will add greatly to their durability, and ata diminishedy cost. e

Having thus described the nature, onstructiou,.aud advantages of our ncw'article of manufacture,

\Vliat we claim as of our invention is- As a new article of manufacture, a bar of iron or steel rolled into the forin herein describe-d and shown, for the purpose of forming a continuous series of blanks for plow-beams. f
